What happens when CFC or HCFC molecules get in the stratosphere & free
atoms of Chlorine are set free? -- ANSWER--These atoms attack Ozone
Molecules causing the formation of Chlorine Monoxide (CLO), after colliding
with another Ozone Molecule, causes 2 Oxygen (O2) molecules to be made &
leaving an atom of chlorine to act as "Free Agent" starting the process over until
100,000 molecules of Ozone are destroyed by just one atom of chloride.
